EndodonticsCervical third root fractures have the least favorable prognosis. This is because: 1) The fracture line is at or near the gingival margin, making restoration difficult, 2) Contamination from oral fluids is inevitable, preventing proper healing, 3) Crown-root ratio becomes unfavorable even if healing occurs, 4) Periodontal involvement is common, 5) Often requires extraction due to poor long-term prognosis. Apical third fractures have the best prognosis as they often heal with fibrous union and remain functional, while middle third fractures have intermediate prognosis.

The Reverse Townes projection is a specific radiographic view used in dentistry and maxillofacial imaging to provide a clear image of the mandibular condyles and the subcondylar region, making it ideal for detecting fractures in this area.

Dental Anatomy
Sometimes, mineralization of dentin begins in small globular areas that fail to coalesce into a homogenous mass. This results in zones of hypomineralization between the globules.
These zones are known as globular dentin or interglobular spaces. Thus, demonstrating defect of mineralization and not of matrix formation, the dentinal tubules pass uninterruptedly through interglobular dentin.

General MicrobiologyPrions are infectious proteins that are highly resistant to destruction by proteases and other methods that typically degrade proteins. This resistance is what allows them to persist in the host and cause disease. They do not contain nucleic acid, which is a hallmark of other types of infectious agents such as bacteria, viruses, and fungi.

Community DentistryThe most common aetiology of oral cancer in India is tobacco products (Answer: 2). The high prevalence of tobacco use, particularly in the form of betel quid with tobacco, paan masala, and other smokeless tobacco products, significantly increases the risk of developing oral cancer.

ProsthodonticsThe Bass technique (sulcular method) is widely regarded as the most effective because it places bristles at a 45° angle into the gingival sulcus, effectively removing plaque from the gingival margin and cervical areas of teeth.
